HER2/neu test - (pronounced) A laboratory test that measures the amount of HER2/neu protein on cancer cells, or how many copies of the HER2/neu gene are in the DNA of cancer cells. The HER2/neu protein helps control normal cell growth. Higher levels of the HER2/neu protein, or too many copies of the HER2/neu gene, can be produced by some cancers, including breast, ovarian, bladder, pancreas, and stomach cancer. This can cause cancer cells to grow faster and spread to other parts of the body. A HER2/neu test may be performed to aid in treatment planning, which may include drugs that target the HER2/neu protein. It's a kind of tumor marker test. Also called HER2 test and human epidermal growth factor receptor 2 test
